SAD-IRON.

SPECIFICATION forming part of Letters Patent No. 662,932, dated December4, 1900.

Application filed February 2, 1898. -Renewed April 7, 1900. Serial No.11.996. (No model!) To a/ZZ whom, t may concern:

Be it known that I, SOLOMON L. GROSS, a citizen of the United States ofAmerica, and a resident of Des Moines, in the county of Polk and Stateof Iowa, have invented a new and useful Sad-Iron, of which the followingis a specification.

One object of this invention is to provide improved means for heatingand maintaining at a heated temperature a sad-iron.

A further object of this invention is to be found in the provision ofmeans for insuring the full and complete vaporization 4of the liquidemployed as the heating medium.

A further object of this invention is to be found inthe provision ofmeans for removing and separating out from the heating medium allsediment or foreign substances in advance of the vaporization thereof.

A further object of this invention is to be found in the provision of a4tank or reservoir made of a single piece of metal by casting.

The objects of this invention, as above stated, are attained by theconstruction, arrangement,and combination of elements hereinafter setforth, pointed out in my claims, and illustrated by the accompanyingdrawings, in which- Figure 1 is a perspective of the complete device inthe form for practical use. Fig 2 is a sectional elevationlongitudinally of the device. Fig. 3 is an enlarged sectional viewshowing screen in trap. Fig. 4 is a plan of the device, the lid beingremoved and the supply-pipe broken off.

1n the construction of the device, as shown, the numeral designates asad-iron formed with the concavity 1l in the upper portion thereof,which concavity is covered by a lid 12,carrying standards 13 14, towhich a handle 15 is attached, a shield 16 being interposed between thehandle 15 and the cover 12. The forward end portion of the cover 12rests beneath a shoulder or shoulders 12a on the upper portion of theend of the sad-iron 10, and

\ the heel of the cover engages with a flange 17 on the heel of thesad-iron and is secured thereto by a set-screw 18, screw-seated in saidange and engaging the rear end of the cover.

A generator is provided and secured to the rear portion of the sad-iron10 by flanges 17 17", extended horizontally laterally from the generatorand fixed by screws or bolts 19 19a to the rear end of the sad-iron. Thegenerator comprises a chamber 20 in its upper forward portion, intowhich is screwseated asupplypipe 21. The supply-pipe 21 extendsforwardly through the concavity 11 of the sad-A iron and is curvedupwardly atils forward end in front of the handle of the device. Areservoir, tank, or receptacle 22 is provided, which is made of a singlepiece of metal, preferably brass, by casting, and is provided with ascrew-threaded hub on its lower end, so shaped as to receive thescrew-threaded upper and forward end portion of the supply-pipe 21. Aboss 23 is formed integrally on the upper end of the tank 22 and has aclosing-cap 24, mounted by screw-seating thereon, a gasket 25 beinginterposed between the bossed portion and closing-cap sealing theentrance to the tank. The chamber 2O is of greater length than theportion of the supply-pipe contained therein and is of-greater diameterthan the interiordiameter of said supply-pipe, thereby forming a trapinto which the sediment and foreign substances of the heating mediumnaturally precipitate and l'emain. The generator further comprises acommunicat-ing port 26, leading from the upper rear portion of thechamber 2O horizontally rearwardly to and communicating with the top ofthe well 27, vertically positioned in the rear portion of the generator.The well is drilled in the generator from the top thereof and closed at"its upper end by a plug28, screwseated therein. The lower end portion ofthe well 27 communicates through a passage 29 with a the rear portion ofthe generator, which discharge-port contains and is controlled by a thegenerator in a plane intersecting the ver tical plane of the well 27,which needle-valve is provided with an angular-outer end portion, soshaped as to be engaged by a key or wrench to rotate said valve. Aburner 31 is centrally located in the concavity 11 of the sadiron and isformed of a tube or cylinder closed at its forward end and open at itsrear discharge-port formed in and horizontally of Y needle-valve 30,horizontally screw-'seated in IOO end, the rear end portion of the tubebeing screw-seated in the forward portion of the generator in alinementwith the needle-valve 30 and in such position as that the dischargeportis axially of the tube. A series of perforations 32 are formed in thelower portion of the burner 3l and directed downwardly therefrom. Avaporiziug-ball 33 is located in the lower portion of the well 27, thediameter of which ball is only slightly less than the diameter of thewell. On the sides of the sad-iron, at the points of contact of thecover therewith,there are formed notches llau to permit of the escapefrom the concavity ll of the vapors and gases produced therein by theoperation hereinafter described.

In practical use I fill the tank 22 with gasi olene, alcohol, or similarfluid, open the discharge-port by the rotation of the needlevalve 30,and open the closing-cap of the tank slightly. The uid then iiows fromthe tank through the supply-pipe 2l into the chamber 20, through thecommunicating passage or port 26 into the well 27, around theVaporizing-ball in the well,through the passage 29 and discharge-portinto a drip-cup 34 in the heel of the sad-iron, and also into the burner3l and through the apertures 32 thereof into the lower portion of theconcavity 11. When a sufficient quantity of i'luid has flowed from thetank, I close the closing-cap and dischargeport and ignite the fluid inthe drip-cup and concavity, the burning of the iiuid heating thegenerator, burner, supply-pipe, tank, and, in fact, the entire device,except the wooden handle.- When the free fluid is about exhausted, Iopen the discharge-port, and more fluid is expelled from the tank by theexpansion thereof, which fluid iiows through the passage heretoforedescribed to the Vaporizing-ball and at that point is vaporized by thevaporizing-ball and the heated metal of the generator and discharged asinflammable vapor through the passage 29 and dischargeport into theburner 3l and through the apertures 32 of the burner downwardly intocontact with the sad-iron immediately below the burner. I ignite theiniiammable vapor at the point of discharge from the burner, and therebyproduce intense heat below the burner upon the sad-iron, which heat isdisseminated through the different metal parts and communicated to alarge degree to the Y tank or receptacle, maintaining such a degrec oftemperature in said tank as to insure the expansion of the fluid thereinto such an extent as to discharge all of said iiuid through theapertures and into the concavity of the sad-iron in the form ofiniiamrnable vapor.

In the provision of a tank formed of a single piece of metal, preferablybrass, by casting, I provide against the explosion or disintegration ofthe tank or separation of its members. In the use of the vaporizing-ballin the well I provide for the complete and perfect vaporization of theiuid in advance of its discharge from the discharge-port, because theVaporizing-ball is heated to a high degree and the Huid must pass aroundsaid ball in a thin sheet, to a maxim um degree susceptible to theheating influence of adjacent metallic bodies.

In the provision of the trap formed by the rear portion of the chamber2O and in conjunction with the communicating passage 26, of very smalldiameter and located at a high altitude relative 'to the bottom of thechamber 20, I have provision for depositing, precipitating, andretaining mineral substances, sediment, and foreign matter contained inthe iuid, and thereby prevent clogging of the minute passages 26 29 bysuch sediment or mineral substances. I also provide ascreen 35 in thetrap or chalnber 20 to interrupt and prevent the flow of sediment to thewell.

I claim as my inventionl. A vapor-burning sad-iron, comprising anoil-tank, a sad-iron provided with a cavity, a generator mounted in therear of said sad-iron and opening to the cavity therein, a supplypipeconnecting the tank and generator and carrying the tank, a burner fixedto the generator and extended into the cavity of the sad iron andprovided with downwardlyopening flame-ports, a trap-chamber in thegenerator at the discharge end of the supplypipe and of greater diameterthan said pipe, a minute communicating passage horizontally positionedin the upper portion of the generator and leading from the upper portionof the trap opposite the supply-pipe, a screen in the trap, a wellvertically formed in the rear portion of the generator, and receivingthe discharge end of the communicating passage, a passage 29 anddischarge-port at the lower end of the well, a needle-valve controllingthe discharge-port, and a generating-ball in the lower end of the well,which ball is of slightly-less diameter than the well.

2. In a sad-iron, the generator having the cylindrical well, ahorizontal discharge-passage below said well and an oblique passageleading from a point at one side of the central Vertical plane of thewell to and. communieating with the horizontal discharge-passage nearthe terminal thereof, a needle valve mounted in and controlling thehorizontaldischarge-passage, a spherical ball of slightly less diameterthan the well mounted loosely in and resting onthe bottom of said well,the point of contact of the ball and well-bottom being at the centralvertical plane of the well, means for supplying iiuid to the generatorand a burner attached to the generator.

3. In a device of the class described, a generator having a trap and awell, a minute passage between said trap and well, a vaporizingballlocated in said well, a discharge-port communicating with the well, anda needlevalve controlling said discharge-port.
